This might be the highest-production boardgame I've seen on tabletop - incredible work!

Personally, I've never played Pokemon myself before but I had to give this a go and sunk several hours into nuzlocke challenge.

Can recommend considering having such a solo mode!

Some rule modifications that I think are fun:

* If your pokemon ends a battle with zero life, it's gone forever.
* If you have no pokemon in your party, game over.
* When catching more pokemon than your party can hold, you can sideboard one of them. The party can be changed in towns.
* You are allowed to switch pokemon in battles for another in your party *instead of taking a move* (i.e. the opponent gets a swing).
* Optionally, replace your starting pokemon with a choice among two random basic pokemon.
* When facing an alpha pokemon, you are allowed to attempt to flee from the battle instead of taking a move - roll a die and get away at 5+. If you do, the alpha is removed from the game.
* Searching at apicorn spots is mandatory.
* After visiting an apicorn spot, remove it from the board.
* Healing a pokemon at town or a traveling healer costs 1 apicorn of your choice per pokemon.
* You can only fly to unvisited towns and this costs two apicorn levels.

Opponents:
* Add one or two opponent trainers. Give them random starting towns and block their towns for Act I. These tokens can not be interacted with and are removed when you clear your hometown.
* At the beginning of the opponent trainer turn, give them a journey point.
* If the trainer has enough points to upgrade a pokemon in the party, pay to do so. If there is none to upgrade, instead add or upgrade attached moves at a cost of 3 each. The moves are taken at randomly but most be compatible. If there are no move to upgrade, instead attach random artifacts at a cost of 3 each.
* The opponent trainer will take two legal moves on the shortest path towards your trainer (randomize if unsure).
* When the opponent steps over an encounter space, roll a die. On 5+, start a random encounter but instead only add it as a member of their party (if any free slots) or else add it as a move (if compatible and an upgrade).
* Permanently remove from the board all of the non-town interactables they step over. This is the price for dawdling around. The opponent trainer does not activate those interactables (no apricorns etc).
* The trainers have as many pokemon slots as you.
* If you and the opponent trainer ever share a space, initiate a trainer battle.
* The trainer is stupid and just plays their pokemon from first to last.
* After being defeated, the opponent trainer is out for three turns. When they are done, return them to their starting town and replace all of their pokemon and moves with random compatible cards of the same level.
* Defeating the opponent trainer adds journey points to you at the level of their highest pokemon.

* Try to discover the legends while surviving!
